Hard disk space
x86 64-bit
Operating system versions
See Where can I install the Cortex XDR Agent? in the
Palo Alto Networks® Compatibility Matrix
Kernel version
Kernel Mode
Version - minimum 2.6.32
To perform malware analysis of ELF files, and collect data for EDR and behavioral threat analysis, the Cortex XDR agent for Linux requires a supported kernel version of 2.6.32-573 or later, as listed in Latest Kernel Module Version Support.
If you deploy the Cortex XDR agent on a Linux server that is not running one of the kernel versions required for these additional protection capabilities, the agent will operate in asynchronous mode.
User Space Mode
Version - 5.0 and above
New Cortex XDR agents and Cortex XDR agents running on versions earlier than 7.7, create and deploy the latest YAML installer for Kubernetes based installations.
Software packages
  • Verify you have standard Unix programs installed.
  • ca-certificates
  • openssl 1.0.0 or a later release
  • Distributions with SELinux in enforcing or permissive mode:
    • Red Hat Enterprise Linux 6, CentOS 6, and Oracle Linux 6—policycoreutils-python
    • Red Hat Enterprise Linux 7, CentOS 7, and Oracle Linux 7—policycoreutils-python and selinux-policy-devel
    • SUSE—policycoreutils-python and selinux-policy-devel
    • Debian and Ubuntu—policycoreutils and selinux-policy-dev
  • glibc—Required for exploit protection of containerized processes using the ROP Mitigation and Brute Force Protection modules. If glibc is not installed, the modules are disabled but all other exploit and malware protection functionality work as expected.
  • CentOS 6.10—Enable the dynamic CA instead of the legacy CA:
    1. Enable the dynamic CA configuration:
      update-ca-trust force-enable
    2. Import the certificates:
      cp XDR-certificate.crt /etc/pki/ca-trust/source/anchors/
    3. Rebuild the certificate database:
      update-ca-trust extract
